| thoracic outlet s. |
any of a variety of neurovascular syndromes resulting from compression of the subclavian artery, the brachial plexus nerve trunks, or less often the axillary vein or subclavian vein, by thoracic outlet abnormalities such as a drooping shoulder girdle, a cervical rib or fibrous band, an abnormal first rib, or occasionally compression of the edge of the scalenus anterior muscle. Continual hyperabduction of the arm may cause another variety (hyperabduction s.). Arterial compression leads to ischemia, paresthesias, numbness, and weakness of the affected arm, sometimes with Raynaud's phenomenon of the arm. Nerve compression causes atrophy and weakness of the muscles of the hand and, in advanced cases, of the forearm, with pain and sensory disturbances in the arm. Venous obstruction usually takes the form of the Paget-Schroetter syndrome. Other types include the cervical rib s., costoclavicular s., and scalenus anticus s.
